About this study

Official title: PRophylactic mEsh Reinforcement Versus Primary Closure After Emergency Midline Laparotomy (PREEMPT): A Multicenter Randomized Clinical Trial

The PREEMPT trial is a multicenter randomized controlled trial comparing prophylactic onlay biosynthetic mesh reinforcement with primary suture closure in adult patients undergoing emergency midline laparotomy. Participants will be randomized in a 1:1 ratio. The primary endpoint is the incidence of incisional hernia at 1 year. Secondary endpoints include postoperative complications, surgical site occurrences, pain, operative time, hospital stay, morbidity, mortality, quality of life, and long-term hernia incidence.

Read the detailed description

Incisional hernia (IH) is a frequent complication after midline laparotomy, with rates up to 50-70% in high-risk or emergency settings. Emergency procedures are particularly prone to IH due to contamination and suboptimal conditions. Prophylactic mesh reinforcement has been shown to significantly reduce IH rates in elective surgery without increasing wound morbidity, but evidence in emergency settings is scarce. Biosynthetic meshes, with favorable safety and cost profiles in contaminated fields, may offer an effective preventive strategy.

The PREEMPT trial is a multicenter, randomized (1:1) controlled study including adult patients undergoing emergency midline laparotomy. Eligible patients will be randomized to prophylactic onlay biosynthetic mesh reinforcement versus primary suture closure. The primary outcome is the incidence of incisional hernia at 1 year. Secondary outcomes include postoperative complications, surgical site occurrences, pain (VAS), operative time, length of hospital stay, 30-day morbidity and mortality, readmission and reoperation rates, and long-term quality of life (SF-36) and hernia incidence at 2 and 3 years.

The PREEMPT trial is a multicenter randomized clinical trial of patients undergoing emergency laparotomy. We aim to evaluate whether prophylactic bio-synthetic mesh reinforcement could reduce the incidence of incisional hernia in patients undergoing emergency midline laparotomy compared with primary suture closure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Prophylactic Biosynthetic Mesh PlacementDevice

    A biosynthetic mesh (poly-4-hydroxybutyrate mesh) is placed prophylactically to reinforce abdominal wall closure during laparotomy closure.

  • Direct sutureProcedure or surgery

    Direct fascial suture closure of the abdominal wall after laparotomy without prophylactic mesh reinforcement.

Study groups in NCT07753551
Study groupRoleWhat they receive
Mesh-repair groupExperimentalPatients randomized to this arm will receive prophylactic onlay placement of a biosynthetic mesh (poly-4-hydroxybutyrate mesh) to reinforce the abdominal wall closure at the time of laparotomy closure, in addition to standard surgical closure. A minimum overlap of 3 cm on all sides of the incision will be ensured. Mesh fixation will be achieved with four sutures placed at the cardinal points only.
Receives: Device: Prophylactic Biosynthetic Mesh Placement
Direct suture groupActive comparatorPatients randomized to this arm will receive standard abdominal wall closure according to European Hernia Society (EHS) guidelines: a slowly absorbable running suture will be used in all centers, employing a continuous small-bites technique. Tissue bites of 5-9 mm from the wound edges will incorporate the aponeurosis only, with stitches placed 5 mm apart to ensure uniform tension distribution, aiming for a suture length to wound length ratio of at least 4:1.
Receives: Procedure: Direct suture

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of incisional hernia at 12 months after laparotomy

    The primary outcome is the occurrence of incisional hernia within 12 months after laparotomy, assessed by clinical examination and/or imaging according to the study protocol. The incidence of incisional hernia will be compared between patients receiving prophylactic biosynthetic mesh reinforcement and patients undergoing standard abdominal wall closure without mesh.

    Measured: 12 months after laparotomy

Secondary outcomes (5)
  1. Postoperative complications

    Postoperative complications will be assessed according to the Clavien-Dindo classification.

    Measured: Within 30 days after surgery

  2. Incidence of surgical site infection

    The incidence of surgical site infection (superficial, deep, and organ-space infection) occurring after laparotomy will be evaluated and compared between treatment groups

    Measured: Within 30 days after surgery

  3. Incidence of surgical site occurrences after emergency laparotomy

    The incidence of surgical site occurrences (SSO), including surgical site infection, seroma, wound dehiscence, hematoma, and other wound-related complications, will be assessed and compared between treatment groups.

    Measured: Within 30 days after surgery

  4. Incidence of surgical site occurrences requiring procedural intervention (SSOPI)

    The incidence of surgical site occurrences requiring procedural intervention (SSOPI) will be assessed. SSOPI include surgical site occurrences requiring invasive treatment, such as wound drainage, percutaneous intervention, surgical debridement, or other procedural management.

    Measured: Within 30 days after surgery

  5. Incidence of incisional hernia at 2 and 3 years after surgery

    The long-term incidence of incisional hernia will be assessed at 2 and 3 years after laparotomy and compared between patients receiving prophylactic biosynthetic mesh reinforcement and patients undergoing standard abdominal wall closure without mesh.

    Measured: At 2 and 3 years after surgery
